Sram Plasm D.I.R.T. Derailer
Has anyone heard of the Sram PLasm D.I.R.T. Rear derailer, it is supposed to be 205grams, I'm thinking of getting one for my Trek because it works with RapidFire and 7, 8 and 9spds. I found it on some discount parts sites, but there is no mention of it on Sram's site as far as I can see.
